I have 'em (Grand Sport offset). For me it was 1) a lot of the BFH, 2) ground down the bump stops some, 2) rolled the fenders. Every car is a little different & depends on what your ride height is and suspension set up too. Also I think TA's have a little more room than Camaros from what I here.

+1, BFH is your friend.
You might want to cut down your bumpstops too. My wheels loved to hit them when I went over any halfway large pothole in the road. Also, buy a panhard rod if you dont have one already, it will keep the rear from swaying as much around corners.

Difinitley grind down the bumpstops!!!! thats the only thing I had to do to mine. The rims will hit the bumpstops everytime you jack the car up by the chassis, or even if you hit a bad pothole. Test fit the rims and you will see where it hits.

DO NOT GRIND DOWN OR REMOVE YOUR BUMP STOPS!!!! They are tapered for a reason (the Z28/Trans Ams are more pointy/tapered than the SLP bump stops). You need them! Removing or altering the bump stops themselves is asking for problems (sliced sidewalls, more fender rubbing, etc.)

Mine fit fine for the lip. I have the SLP Bilstein/Eibach combo. Now as for the BS, its rubbing on the inside of the rim. I need to get an air tool and do some grinding of the bs. Its either that or get some spacers.

i have them and you gotta do the same stuff that every one is saying but i cut my bump stops of and have never had a problem with the inner side of the tire and im runnig gsd3s that are much wider than most 315s...now the outer fender was a different story
